SIGNAL-LAM P.

SPECIFICATION forming' part of Letters Patent No. 266,719, dated October 31, 1852.

(No model.)

To all whom it may concern Be it known that I, EDWARD SPENCER PIP- ER, a subject of the Queen ot' Great Britain, residing at the city of Toronto, in the county of York, in the Province ot' Ontario, Dominion of Canada, have invented certain new and useful Improvements in Signal-Lam ps,ot'which the following is a specification.

The object of my invention is to produce a lalnp arranged to give lig'ht to the interior oi' a car or coach, and at the same time furnish light for two bulls-eye or signal lenses, provision being made for changing the color of the signal and for making one signal invisible while the other is exhibited, the whole being' arranged so that each part ot' the lamp and its attachments are accessible from the interior of the car; and it consists essentially ot' a lamp-box placed on the outside of a car, and communicating with the interior ofthe car through a hole made in the side, the said box having placed within it a lamp situated between two .signal-lenses, each lens being provided with a reflector formed in the shape of a frustum ot' a cone, so as to permit the light from the lamp to reach the lens, while preventing the color of the lens on the opposite side being seen through, the attachments for aecomplishing `the ends of my invention being arrangedsubstantiallyas hereinafter more particularly described.

ln the drawings, Figure l is an end view of my lamp-box, showing it applied in position on the side of a car.- Fig. 2 is an inside view of my lamp-box, showing it as it will appear from the interior of the ear. Fig. 3 is a crosssection ot' my lamp box and lamp. Fig. 4 represents in detail the manner of holding the signal-lens and reeetor in position. Fig'. 5 is a detail of the signal-glass.

In the drawings like letters indicate corresponding parts in each figure.

A represents the wood-work on the side of a car.

o B is a lamp-box, open on one side and screwed to the wood-work of the car, so that its open side shall face the interior ofthe car, the woodwork being cut Iaway to form a hole corresponding with thc open side ot' the lamp-box.

O is a glass cover or door, arranged to close the open side of the lamp-box, so as to protect the lamp D within the lamp-box, while permitting its light to be reiiected into the car, the

back ot' the lamp-box being provided with a corrugated or otherwise suitable reector. A t each end of the lamp-box, opposite to each other and having the lamp l) between them,

are two holes made in the lamp-box and pro-l tected by suitable lenses, E. ln order to hold the lens in position, I place around each hole in the lamp-box a flanged ring, a, having a thread or screw cut on its inner surface to receive the ring I), each ring being provided with two lugs, d, to enable the rings to be unscrewed as required. The lenses E, which are flanged f'or that purpose, lit against the iiange ol" the ring a., while the flange on the reilector F rests against the tlange of lens E. These are first putin position from the interior ot' the box B, when the ring b is screwed into position, compressing the reflector F and lenses together, forming a tight ljoint around them.

G is a signal-glass contained within a frame, provided with hoop-wires g. These wires g are designed to fit into holes made in the reflector F, for. the purpose ot' holding the signalglass over the hole made in the reflector F. As the signal-glass is easily detached and put in position again, it will be seen that thenaturo ot the signal can readily be changed by altering the signal-glass. For instance, when it is desired to give a danger signal the i'ed glass may be hung in position, which glass can readily be removed, when finished with, and replaced by a glass ot' ditt'erent color.

When it is desired to shut ott' the light from either of the lenses a blank cover is hung on the reiiector F in the same manner as the signal-glasses Gr, completely cutting oli" the light.

In order to hold the signal-glasses not in use, 1 provide a pocketJL, formed in the root' of the lamp-box, so that while being out ot' the way the glasses are readily accessible from the interior of the car.

\Vhen a lamp with a glass is-used l provide a semicircular hood, H, placed on the roof ot' the lamp-box B, around the mouth ot' the upper ventilator, l, into which the top ofthe chimney projects, the said hood being designed to prevent sudden gusts of wind reaching the top ot' the glass when the door O is opened.

With the view ot' indicating the quantity of oil contained in the lamp,I form inthe interior of the oil or Huid reservoir a tube, j, which eX- tends down to the bottom of the reservoir and is perforated, so that the fluid in the oil-reservoir is admitted into the tube.

7c is a float. made of' cork or other suitable material, and -provided with a spindle, Z,which extends through the top of the oil-reservoir.

mis a lange formed around the aperture through which the spindle passes. As the oil in the tube will be the same height as that within the reservoir, and as the float k will swim on top of it, the length of the spindle eX- tending above the reservoir will indicate the height of the oil Within it. Should the lamp be upset, the float comes in contact with the flange on, thereby closing the aperture and preventing the oil escaping.

The manner of' securing the bulls-cye E and retlectorF together, and both to the box-casing, in this construction is an improvement upon the patent granted to me November 22, 1881, No. 249,794fas in that construction the holding-flange was a portion ofthe screw-ring and had to be manipulated from the outside. The present construction makes the holding-flange a portion of the permanent casing, and the screw-band is manipulated from the inside of' the car or coach.

I do not in this application claim the float K and its containing-tube, as described, as I intend to le a separate application embodying this feature.

What I claim as my invention is 1. The lamp-box having a contained lamp, and having a permanent holding-fange for the lenses and internal screw-threads, the lens E and screw-rin g b, adapted to be secured in place from the inside of the box, combined with a car or coach having an opening in the side thereof` corresponding with the opening in the lamp-box, as set forth.

2. A lamp-box containing a lamp and attached to the outside of a car or coach having a hole through its side to communicate with the interior ofthe box, the said box being provided with a signal-lens protected by a reflector formed in the shape of a frustum of a cone, in combination with the signal-glass G, detachablyr connected to the relector F, substantially as and for the purpose specified.

3. In alamp-box containing a lamp and provided with a si gnal-lens protected by a reflector formed in the shape of a frustum of a cone, a signal-glass, G, contained Within a frame provided with a hoop-Wire, g, in combination with a hole or holes made in the reector F for the purpose of forming a detachable connection between the signal-glass and reflector, substantially as and for the purpose specified.

4t. In a lamp-box containing a lamp and having a circular hole or holes pierced through it, a flanged ring, a, formed around each hole and having a thread cut on its inner surface to receive the screwed ring b, in combination with the hanged lens E and langed reflector F, for the purpose of' protecting the hole in the lamp-box, as specified.

5. In a lamp-box containingalamp provided with a chimney and a door to give access to the interior of the box, a semicircular hood, H, formed on the interior roof of the lamp-box around the mouth of the upper ventilator, substantially as and for the purpose specified.
